axcrrporatioirof New Jersey Applicatie Merch 7 1959. Serie? Nr- 148063 i grain. (c1. 22o- 66) This invention is an 'outlet for milk delivery canswof the'general eharacterY disclosed in my prior Patent No. 2,282,836. v'Ihis patent discloses a can'from which milk may be dispensed through a discharge tube vextending through the side' wall of the can near the bottom thereof. The tube is slidable into and outof the can through a leak proof gasket carried by a vsheet metal cupV permanently attached to the side wall of the :can and projecting into the confines of the can.

The structure shown in this patent operates with higheicien'cyand is acceptableto the Boardsr of Health of most places. In certain localities, however, the Board of Health regulations require that' the interior of the" can must be absolutely flush throughout and the can of my said prior patent will manifestly not conform with this regulation becaiise'f Athe .protrusion oi the c up into the interior of the can.

The present invention overcomes this objection by so arranging the cup that its inner end is flush with the inner surface of "the side wall of the can and at the same time the cup is adequately supported on the wall .of .the can against the hard Wear and tear to which milk cans are subjected in use. These cans be made initially to embody the present inyention, but it is generally found desirable to l.produce .them by conversion of conventional milk 'delivery'eans of the twenty or forty quartvariety intoside delivery cans embodying this invention. This invention includes a novel method of accomplishing the conversion of such Ial'eronventionalcan- Features of the initei'ition,l other than those adverted to, will .be apparent from ,the hereinafter detailed description and fappended'claim, when read in conjunction with the accompanying drawings.

The accompanying drawing illustrates one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as defining the limits of the invention.

Figures 1-6, inclusive, are fragmental perspective sections showing consecutive steps in the method of modifying a conventional milk delivery can to permit it to be used as a side delivery can as stated.

Figure 'I is a face view of a cup supporting boss shown as secured to the can in several of the I preceding figures.

Figure 8 is a section on the line 8-8 of Figure 7.

Figure 9 is a bottom view of a reinforcing plate shown in the form of a sheet metal stamping adapted to be secured lo the bottom wall oi the canin the rgit-nef the" @heropening VInY the accompanying drawing, VI designates the side walll 'of 'a' conventional' milkifdelive'iy can. This wauijs of cylindrical frr''ancrispifovided at its 'top with the usual breast'abc'ivev which projects the'neck of the can.' surdnounted bia lip. A can of vthis general" character is'fshowri in William Tamminga Patent No.' 2,186,082.7'-The can has a vclosed bottom? which is' dished down'- wardiy mm its periphery 'and the never-perrita of the periphery of the side wall' ofthecanis' commonly embraced bym;E reinforcing ring '3 welded or otherwise permanently'secred t'os i Side Waui U In Figures 1-6 of the drawing a vc.Qrn'entional form of can is shown wH- iein the bottonis formed integral witli'the'side'walls. In' A' cases, .the bottom 'is' formed' separately" provided with a 'depending' innigev perman nur " exea to the side walls. *in other' casesg'ihe-"sds wall extends to the" very bottom ofthe fea'nand a reinforcing Aring is positionedinsideoj! the de wall and below the can bottom. Thse, however',

are details oflconstruction' relating generallyto the diierent waysV inwhichiconventionalcans are made' and itis 'to be understood thatfthe pres'- ent invention may be' associated with any known form of' conventional can.

In carrying out the method of this invention" with a`can as shown, a rshort arcuateslit Us first made along a line where the' bottom 2' jdins the side wallll; as indicated .in Figuiell." slit extends entirely through the bOtt'oin ofthe can and Yfollows* the lplane vOf 'the .,SY/.llV-L After' the sin has been mail?, that portmndfytlie bottom of the'can between the termini ol.' the arcuate slit is pressed downwardly to form a channel 5 of arcuate cross section, as shown in Figure 2. This channel, of gutter, as it is sometimes called, extends from substantially the center of the can and the bottom of the channel lies substantially in the plane of the lowest portion of the can bottom, so that milk may drain through said channel from the center of the bottom 2.

After the channel has been formed as stated, a hole 'l is cut through the side wall of the can and through the reinforcing ring 6 which is.l

shown as permanently secured to the exterior oi' the side wall. This hole 'l substantially registers with the channel 5, but is suiciently large to receive the base of the cup 8. Figure 3 shows the relation of the opening 1 to the channel 5.

There is next aixed to the exterior surface of of the boss are preferably sloped, as shown at l i,

and this sloping may extend entirely around the boss if desired, so that, when the boss is in place on the can, objects striking the boss will slide off of the same rather than tend to dislodge the boss from the can.

The boss is secured to the can by the step shown in Figure 4, the central opening I being brought into registration with the opening 'l in the side of the can and the boss thereupon welded, soldered or otherwise permanently mounted coaxially of said opening l, I preferably also secure the boss to the can by rivets I2 which pass through rivet holes I3 formed in the boss and through alined holes in the ring 6. The purpose of these rivets is to assist the solder, weld or other attachment in permanently securing the boss in place, so that it cannot be knocked 01T if struck byv or against some extraneous object.

The thickness of the boss is such that, when applied to the can, as shown in Figure 4, and the cup 8 introduced, as shown in Figure 5, the other ange ill of the cup will seat against the outer surface of the boss while the ilange l at the inner end or base of the cup will be flush with the inner surface of the side wall l of the can. The cup is secured in this position by welding or soldering it permanently in place and in this soldering operation, solder is flowed into the joint between the inner portion of the cup and the side wall and bottom of the can so as to form a liquid tight joint therewith.

Having thus applied the boss and cup and rmly and permanently secured them in place, I next apply to the under surface of the bottom of the can a reinforcing plate l5, shown in Figure 9. This plate is stamped from sheet metal, so as to conform to the bottom of the can and the channel 5 thereof and to underlie said channel when in place on the can. The reinforcing plate may be conveniently secured in position by sweating it or soldering it in place. It serves to render the channeled portion of the can very rigid and it protects said channel against damage in the event that the can is set upon an uneven surface or some upwardly protruding object, such as protrude into the interior of the can. This can meets all the requirements of those localities '4 where a ilush interior can is required and it provides adequate mounting for the cup and effectual protection against damage of any of the parts even when the can is subjected to hard usage.

The annular cup supporting boss which I have shown in the drawings is made solid and this I prefer, although it may be cored or stamped from sheet metal without departing from the invention. Furthermore this boss is shown as substantially equal in height to the height of the reinforcing ring 6, although, in practice, it may extend above this ring and the top of the boss may have a greater slope than as shown if this is desired. For these reasons and others, the invention is to be understood as fully commensurate with the appended claim.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

A single walled milk delivery can having a side wall with a reinforcing ring embracing its lower margin and a dished bottom with a channel leading from substantially the center of the can to the periphery of the bottom and there substantially registering with an outlet opening in the side wall of the can and through the reinforcing ring, a boss welded onto the exterior of the reinforcing ring and having an opening registering with the outlet opening in said ring and in the side wall of the can, and a discharge tube cup seated in and welded to said boss with the inner end of said cup provided with a cross-axial internal flange positioned flush with the inner surface of the side wall of the can.
